SHOCK ABSOR-BER.

Application filed May 1,

T0 all whom z't mag concern Be it known that I, CHARIES W. LAKE, a citizen of the United States, residing at McPherson, in the county oi:' M0Pherson and State of Kansas, have inve'nted a new und useful Shook Absorber, of which the foilowing is a specification.

Ehe present invention relates to shook absorbers, and is mor e particularly a rebound retarder or snubber.

The applicant is aware that attempts hav beenmade to retard the rebound of the cushioning springs of vehioles and that devices have been devised to acoomplishthis purpose. The object of the present inven aion, hoWever, is the product'ion of a rebound retarder for vehicles consisting of fewer parts, thus being more economical to manufacture than those previously pro" posed, and which is attacha-ble to vehicles of all makes with extreme ease and celerity without necessitatin channin detachin o t)? t:

o1" removing, any ofthe existing parts of vehicies, and at' the same time being most efficient for its purpose and in operation.

One of the features of the present invonvention is thatthe operationof the oushioning springs, or other means, of the v'ehicle, due to' thevehicie running over uneven surfaces or to vibrations underload, are not re sisted or retarded in any way.

The irivention broadly resides in a bar ha'ving one end portion pivotally connected to the frame orbody of the vehicle and extened to 1ie under the axle, the other end portion of the bar being resiliently conneoted to the frzune O1 some other stationary part of the vehicle. In practice the best results are obtained by having the bar engage the under side of the axle and slightly under tension while the cushioning means or springs o1" the vehicle are in their normal position, thus rendering ehe invention m'0re sensitive and responsive to the slightest rebounds and eliminating rattling and knocking of loose arts, a1; all times.

The invention furth'er resides in the sundry detai1s of construction, combination and ahnngement-of parts which 2L1e set forth indetail in the following specification.

In this speoification and the annexed drawings, the invention is disclosed in the form in Which it is considered to be the best, but the invention is not limited o0 such form beczuise it is capable of being embodied in other forms; and it is to be understood that 1922. S6rial N0. 557,695.

in and by the claims following the desoription herein it is intended to Cover the invention in whatever form it may embody within the scope thereof.

In the drawings whioh illustrate the proved embodiments of the. invention as ab present devised:

Figure 1 isa perspective View of the in vention unatpplied to a vehicle.

Figure 2 is a plan view of a Ford ohassis equipped with the invention.

Figure= 3 is an enlarged detail fragmentary;side viewof a Ford. chassis equipped with the invention.

Figure 4: is a side vie w of the standard automobile chassis equipp'ed With the invention.

Figui*e 5 is a; large detailed view oif the supporting arm of the invention.

Figure 6 is an end view of the supporfiing arm shovvn in Figure 5 with portion broken away and shown in section.

Figure 7 is a fragmentary front view of Ford chassis equipped with the invention.

Figure 8 is a fragmentary detail view of a modified form of attaching the invention to an automobile frame or chassis.

Like charaoters denote similar and like parts throughout the specifications and drawing.

The form of the invention shown in Figure 1 is particularly adapted for Ford automobiles but oan be applied and used on other types of automobile's with equal facility and giving equal results, and consists in a supporting arm 1 secured by means of a plate 2 to a side frame or other suicable part of an automobile chassis or body. The arm l, preferably, depends r"rom the frame downwardly to a plane substantially adjacent in horizontal plane of the axle A of the vehicle. Y

The 1ower end portion of the supporting arm 1 has pivotally secured thereto the lever 3 adapted to extend, when the device is applied, in a substantially horizontal direotionand underlie the adjacent axle of the vehicle. The other end portion of the lever 8 is suit-ably conneoted to a spring 4 which is 130 be attaohed to some rigid or stationary portion of the chassis or body of the vehiole, as clearly shown in Figure S of the drawing.

The arm 1 preferably has an adjusta'ble connection with the plate 2 in order that ii: can be raised and lowered to effect a genera1 adjustment of the lever 3 with respect t-o end portion of said lever adapted 130 be cannected to said frame and t0 be positioned 011 the opposite side of said axie relative eo said arm, and a stop member 011 said arm f01 limiting the downward swinging movement of said lever, whereby the 1at-ter is prevented from contacting with the ground.

3. A shock absorber 0f the kind described comprising a supporting arm to be secured t0 the frame 0f a vehicle and extend downwardlyfor a distance therefrom, a lever having 0ne end portion pivotally conne'cted t0 said arm and to extend in a substantially horizontal direction t0 underlie an ax1e 0f the vehicle, a oension spring having an ad justable connection with the other ehd portion of said iever and adapted to be attachecl to said frame and positioned 030 the opposite side of said axle relative 130 said arm, said arm havin means whereby it may be adjusted vertmally with respact t0 said frame.

4. A shock absorber attachment for automobiles comprising a cross bar to be secured t0 an end 0f the automobile frame and to extend transversely across the Same, Wii;h the ends of i;he latter ext-ending outwardly 011 one side 0f' the adjacent axle, a pair of levers, one f0r each side 0f the automobile 130 underlie ancl normally engage tha adjacent axle ahereof between their ends, each having one end portion thereof pivotally connected to said frame at a point on the other sicle 0f said adjacent ax1e, resilient connections between the other ends of said levers and the corresponding end portion of said cross bar.

In testimony whereof I have hereunto sei;

my band.
